Pin Router for a Sears Radial Arm Saw

Step 10 The pin

The guide pin would be the same diameter as the router bit.  A dowel can suffice.  Mount it in a piece of plywood and align the pin with the router bit so the bit is directly above the pin.  Fasten the plywood to the saw table so it does not move.  Raise the saw arm with the crank under the saw's table.  Place the pattern over the pin.  Turn the router "on" and lower the arm so the bit cuts in the work piece at the desired depth.  Follow the pattern below until it is reproduced in the work piece.  

I do not use a pin router often, but this is an economical alternative to a commercially produced pin router and works very well.
